Lamp Status
When then unit is On, the returned packet (27 byte long) is described in the following table:
1E BE EF 10 13 00 ..
..
01 01 00 01 01 15 01 00 01 10 00 00 00 UU UU ..
SS LL LL
0
1
17 18
20 21 22
24 25 26
where bytes marked with .. are not relevant.
The response may be separated into 4 parts:
1 bytes (byte 0) that initiates the packet (1E)
17 bytes (bytes 1{17) that duplicate the sent command (apart from 2 of them | the CRC)
3 Error bytes (bytes 18{20) that signal errors in the processing of the command
5 Data bytes (bytes 21{22, 24, 25{26) that contain the requested data
If the 3 Error Bytes (bytes 18{20) are 00 00 00 then requested data are valid.
The tables below explain the meaning of returned data.
Bytes 21 and 22 (labelled UU UU in the table above) contain Unit Working Hours. UU UU is the hex
representation of the number of working hours. Therefore, if, for instance, UU UU = 09 D8 then Unit Working
Hours is 2520.
Byte 24 (labelled SS in the table above) contains the Lamp Status:
Off
00
Ignition 01
On
02
Bytes 25 and 26 (labelled LL LL in the table above) contain Lamp Working Hours. LL LL is the hex
representation of the number of working hours. Therefore, if, for instance, LL LL = 01 B6 then Unit Working
Hours is 438.
